You’re within the examination room at your physician’s workplace. Possibly it’s for an annual check-up. Possibly you’re there for a selected concern. Then it occurs. Possibly the physician prefaces it by asking permission to debate your weight. Possibly they lower straight to the chase (“There’s a drug I feel you’re a superb candidate for” or “Have you ever thought-about taking a GLP-1 to assist along with your extra weight.”)
I truthfully don’t know what they’d say, precisely, simply that they’d both strategy the subject not directly or instantly, they usually may both attempt to cut back the quantity of stigmatizing language they use, or they may not even care about that.
Both means, there it’s. The subject’s been broached, the advice is on the market. What do you do subsequent?

Take a breath and ask some questions (if you wish to)
You could possibly say “No.” Actually “No,” in the event that they requested a yes-or-no query, or “This isn’t one thing I’m taken with/I wish to focus on” in the event that they requested an open-ended query.
Possibly you’re not taken with pursuing weight reduction in any type. Or, perhaps sufficient in regards to the treatment that it’s not for you.
Once more, you’ve got physique autonomy, you’ve got the appropriate to say no.
However what if you happen to don’t wish to shut down the dialog? Possibly you’re curious, or perhaps you’ve already thought-about one in every of these medicines? Right here’s what I recommend.
Ask your physician why they’re recommending this treatment. If you’re at the moment residing in a fats* and wholesome physique, they usually say one thing about how your present weight will have an effect on your future well being, that’s a crimson flag. They’re a doctor, not a psychic. That’s why you’ve got preventive well being care, to observe for any actual well being issues which might be ACTUALLY rising.
*I exploit fats as a impartial descriptor of physique measurement, as a result of the O-words medicalize physique measurement no matter an individual’s precise well being standing.
Additionally, there ample analysis that when individuals comply with fundamental health-supportive habits — consuming ample fruit and veggies, being bodily lively, avoiding tobacco and consuming alcohol sparsely (or under no circumstances) — the affiliation between weight and danger of dying prematurely begins to stage out between the completely different BMI classes.
And if you happen to’re not at the moment following all these health-supportive habits, effectively, that’s one thing tangible and actionable that you might work on. That could be a superb dialog to have along with your physician.
It’s price stating that individuals with regular blood sugar or blood stress or ldl cholesterol don’t begin taking medication for diabetes or hypertension or excessive ldl cholesterol simply because they’re at elevated danger for a kind of situations.

Knowledgeable consent: understanding GLP-1 medicines
You may ask your physician what’s going to occur if you happen to resolve to take the drug however later resolve to go off it. If they are saying something in regards to the drug
- Decreasing your physique’s weight setpoint completely, or
- “Jumpstarting” weight reduction when you work on eating regimen and life-style modifications to take care of it
…then they don’t perceive how the drug works, and shouldn’t be prescribing it to anybody.
I’ve it direct from an ob*sity medication specialist at one of many nation’s most prestigious universities — the GLP-1 doses authorised for weight reduction decrease somebody’s weight set level (the load your physique will comfortably settle at whenever you’re consuming and exercising in a non-disordered means) whereas they’re taking them. But when they cease taking the drug, their set level will revert to what it was earlier than and they’re going to regain any weight they misplaced.
The medical trials that comply with contributors after they’re not on the treatment bear this out — they regain the load.
What if you happen to are taken with a GLP1?
OK, let’s say you might be probably taken with taking one in every of these medicines. A number of persons are, in any case. I’m not going to lie, I’ve some considerations about them, however within the decrease doses advisable for diabetes therapy, they’ve helped lots of people.
That stated, if you’re contemplating taking a GLP-1 within the larger dose for weight reduction, there are two main issues that I want for you:
- That you’ve all the data it’s essential to make a really knowledgeable choice. Actually understanding GLP-1 medicines earlier than taking one is necessary. As a result of if you happen to consent to one thing, however you don’t absolutely know what you’re consenting to, are you actually consenting?
- That you’ve the help it’s essential to take care of any of the frequent uncomfortable side effects (nausea, constipation and so on.) that you just may expertise, and to just be sure you are consuming sufficient to fulfill your dietary wants (extra on this in a bit).
Let’s begin with #1.

Let go of any magical pondering
Let’s begin with the truth that GLP-1s should not magic. They’re medicines/medication that produce completely different outcomes (together with each weight reduction and uncomfortable side effects) for various individuals.
Wanting total on the medical trials for the GLP-1s at the moment authorised for weight reduction (so, at larger doses than what’s prescribed for diabetes), individuals lose between about 0% and 22% of their beginning physique weight.
That’s proper, some persons are “non-responders.” The medication do nothing for them. Different individuals lose round one-fifth of their physique weight.
Opposite to unhealthy data floating round on the market (together with one irresponsible article on OprahDaily), individuals don’t lose half of their physique weight.
That signifies that the individuals these medication are supposed for, the people who find themselves in the next BMI class, won’t change into “skinny” by taking these medication.
Let’s do some math. If somebody weighs 300 kilos and loses 20% of their beginning weight, they’ll nonetheless weigh 240 kilos. Not skinny. If they begin out at 250 kilos, they’ll nonetheless weigh 200 kilos. Additionally not skinny.
However what in the event that they’re one of many many individuals who lose 5% of their beginning weight. Then we’re 290 kilos or 237.5 kilos. Not skinny.
Additionally — and that is necessary — these medical trials additionally had contributors create a calorie deficit by reducing energy (aided, in fact, by the discount in urge for food) and rising train. That’s proper, they had been weight-reduction plan AND taking the medication.
In truth, I not too long ago learn an interview with an ob*sity medication specialist from one other prestigious college who stated the aim of those medication is to make it doable for weight reduction from eating regimen/train/life-style to be maintained as an alternative of regained.
As a result of it took the debut of those medication to make the ob*sity medication discipline lastly admit out loud that diets don’t work.

Not hungry? You continue to want meals
GLP-1s’ fundamental actions — performing on the mind to scale back urge for food and slowing abdomen emptying to extend satiety — make it doable to eating regimen with out feeling hungry on a regular basis or making your physique go into hunger mode and begin slowing your metabolism.
Now about that urge for food. A number of issues to know:
- The preferred GLP-1 medicines are longer-acting, requiring an under-the-skin (subcutaneous) injection solely as soon as per week. Some individuals discover that their urge for food flares in direction of the top of every week.
- Some individuals who must cease taking the treatment (extra on that in a bit) discover that their urge for food comes roaring again in a means that I’ve heard described as a ravenous tiger or a tsunami. This will really feel scary.
- Some individuals discover that the appetite-suppressing results of the drug work a bit of too effectively, leaving them with just about no urge for food in any respect and/or forgetting to eat till they only find yourself grabbing a handful of popcorn.
Let’s discuss that final one. Even when you’ve got no urge for food, your physique nonetheless wants gasoline (energy) and vitamins. That’s true whether or not you haven’t any urge for food as a result of you’ve got the flu, you’re grieving, or you might be on a GLP-1. Besides with the primary two you’re going to get your urge for food again a lot sooner.
Our cells want micronutrients (nutritional vitamins and minerals) to perform. Our bones want vitamins to remain sturdy. Our muscle tissue want protein to not wither. Your cells, bones and muscle tissue don’t let go of these wants simply since you don’t really feel like consuming. That’s true for anybody underneath any circumstance.
It may be tempting to suppose, “No urge for food? I don’t should trouble to eat. Nice!”
No, not nice. And when this state of affairs occurs, to guard your well being one or each of this stuff must occur:
- Your physician must decrease your dose.
- You should work with a registered dietitian to determine how one can meet your dietary wants on fewer energy whenever you don’t actually wish to eat in any respect.
I seemed this up, and the minimal advisable energy for a lady on these medication is 1,200-1,500 energy. For males, it’s 1,500 to 1,800 energy. And whenever you’re consuming this few energy, these energy must REALLY rely nutritionally.
(And, no, you may’t simply pop a multivitamin. Whereas that will present some further dietary “insurance coverage” when somebody has bother consuming, remoted vitamins aren’t an efficient 1-to-1 swap for vitamins from meals.)
A registered dietitian can even provide help to take care of frequent uncomfortable side effects resembling nausea and constipation by making the appropriate meals selections.

Some uncomfortable side effects are uncommon, however they’ll nonetheless occur
So let’s discuss extra about uncomfortable side effects. We’ve lined the commonest ones (nausea, constipation, excessively low urge for food + early satiety). You’ll have heard about different, scarier, uncomfortable side effects, resembling paralyzed or blocked intestines, blindness, suicidal ideation.
I’ve dug via the newest analysis, and it looks as if suicidal ideation isn’t the priority it was initially regarded as (however anybody eager about taking a GLP-1 ought to let their physician know in the event that they’ve suffered from despair). The attention factor seems to be extraordinarily uncommon.
Gastroparesis
Gastroparesis is when your abdomen turns into paralyzed. Whereas the danger of that is comparatively uncommon, it’s 4 occasions larger whenever you’re taking a GLP-1. So is the danger of bowel obstruction. The danger of growing pancreatitis, which is when your pancreas turns into irritated and infected, can also be 9 occasions larger in GLP-1 customers.
I’ll add, 4 occasions larger than what? 9 occasions larger than what? These are nonetheless uncommon in GLP-1 customers, however they’re all very critical uncomfortable side effects, and nobody can simply assume “Oh, that received’t occur to ME.” None of us are particular unicorns to whom completely different guidelines apply. It’s simply actually necessary to imagine that you might be one of many unfortunate ones, and are you sufficiently at peace with that chance? Once more, that’s a part of knowledgeable consent.
Hair loss and sagging pores and skin
Within the much less critical, however nonetheless not enjoyable camp of uncomfortable side effects are hair loss and sagging pores and skin. Each of those can occur each time somebody loses numerous weight, nevertheless it’s unclear if and when the hair grows again.
Additionally, opposite to some myths I’ve heard, these medicines don’t additionally “shrink” your pores and skin. So anybody who does lose numerous weight on these medication (and never everybody does), might have to think about cosmetic surgery if the surplus pores and skin is uncomfortable or in any other case problematic.

What if you happen to cease taking a GLP-1 treatment?
A part of knowledgeable consent is knowing that lots of people who take GLP-1s cease taking them inside a 12 months. That’s extra prone to occur with people who find themselves taking the weight-loss doses (not the decrease diabetes doses).
Whereas estimates from the varied analysis research on this phenomenon fluctuate, it hovers at about half of people that take the drug for weight reduction solely stopping inside a 12 months. Current analysis has additionally proven that many individuals who cease accomplish that earlier than they’re even on the most dose and earlier than they’ve reached regardless of the most weight reduction could be for them.
- Some individuals cease as a result of even the frequent uncomfortable side effects (nausea, constipation) should not one thing they wish to proceed experiencing.
- Others may not see sufficient early weight reduction to really feel that it justifies staying on the drug (particularly if in addition they have uncomfortable side effects).
- Nonetheless others cease as a result of they misplaced entry to the drug (they misplaced their insurance coverage, modified jobs and insurances, and so on.).
There’s additionally some B.S. with some insurance coverage firms refusing to cowl GLP-1s for weight reduction anymore as soon as somebody reaches a weight that will not qualify them for the drug in the event that they had been searching for it for the primary time. That is bananas, provided that these medicines are supposed to be continued for all times. And these medication are costly out-of-pocket.
Let’s think about all of this. What would you do if you happen to selected to take a GLP-1, you misplaced weight, and also you needed to discontinue it for one of many causes I discussed? How would you deal with regaining the load and probably having a depraved rebound urge for food?
Pondering this via is a part of making an knowledgeable choice about whether or not to take one in every of these medicines.

These medication should not magic, Half 2
GLP-1 medicines (at each diabetes doses and weight reduction doses) have direct advantages for sure well being situations, resembling heart problems and liver illness. They seem to even have advantages for decreasing substance use dysfunction.
Aside from the noticed profit for obstructive sleep apnea (which, sure, could be improved by weight reduction in larger-bodied people, however can be managed with a C-Pap machine), it seems that, once more, these medication have DIRECT results on these situations. In different phrases, the advantages aren’t because of weight reduction.
So, a query to think about is: Do you’ve got a well being concern that GLP-1s would work instantly on? If that’s the case, what are different therapy or prevention potentialities?
I’ve an acquaintance with a robust genetic predisposition to liver illness. Her father needed to have a liver transplant. She’s in a barely bigger physique and was not taken with reducing weight. She began taking a decrease dose of a GLP-1, and her liver enzymes reverted to regular ranges. She stated she was having some manageable uncomfortable side effects, but when being on that drug means she by no means has to have a liver transplant, it’s price it. She additionally has polycystic ovary syndrome (PCOS), and it’s helped with that (not stunning, since GLP-1s had been initially authorised for kind 2 diabetes, and PCOS is a associated well being situation).
I do know different individuals who had been supplied a GLP-1 as a result of they’re in bigger our bodies and have a well being situation which may be helped instantly by the drug. They selected as an alternative to have a dialog with their physician about their present danger stage, and what their different choices are (together with continued monitoring with preventive well being screenings). They determined GLP-1s weren’t for them, at the least not at the moment.

Last ideas + physique picture
Each eventualities above are examples of creating an knowledgeable choice and giving knowledgeable consent, though the eventual selections had been completely different.
That’s as a result of knowledgeable consent shouldn’t be blind consent. It’s not saying “sure” as a result of your physician desires you to. It’s not saying “sure” since you’re seduced by “earlier than” and “after” photographs of a celeb or an on a regular basis one that’s taking a GLP-1. It’s not saying “sure” on what you hope will occur whenever you actually don’t know the vary of doable outcomes and are available to phrases that you just don’t actually know what your private final result will likely be.
I so ardently need individuals to make the choice that’s proper for them based mostly on stable data that I wrote this actually lengthy article (2,713 phrases).
I additionally ardently need individuals who do select to say “sure” to a GLP-1 weight reduction treatment to have the help they should climate any doable storms of uncomfortable side effects and plummeting urge for food. I would like individuals to maintain their muscle tissue and bones and get the vitamins they should help their total well being, cut back danger of persistent illness, age healthfully, and all that jazz.
Physique dissatisfaction
I additionally need individuals to know that in the event that they battle with physique dissatisfaction, poor physique picture, no matter you wish to name it, these medicines don’t heal that. Even if you happen to’re one of many individuals who lose 20% of your beginning weight on a GLP-1, as weight reduction slows and stops and you compromise into your newly completely different physique, the rumbles of dissatisfaction will in all probability develop louder. That’s as a result of the best way to heal a troublesome relationship along with your physique isn’t to alter your physique, it’s to deal with the underlying wounds and beliefs that made that relationship troublesome to start with.
So if you happen to say “sure” to a GLP-1 (or any type of weight reduction), please be sure to additionally do the therapeutic work.
